“Jace?"
"Yeah?"
"How did you know I had Shadowhunter blood? Was there some way you could tell?"
The elevator arrived with a final groan. Jace unlatched the gate and slid it open. The inside reminded Clary of a birdcage, all black metal and decorative bits of gilt. "I guessed," he said, latching the door behind them. "It seemed like the most likely explanation."

I promise you this is the least of what I can do.”

“So you're a Shadowhunter,' Nate said. 'De Quincey told me that you lot were monsters.'
'Was that before or after he tried to eat you?' Will inquired.”
